2 Claims. (01320-45) This. invention relates to improvements instorm'window' frame construction and is particularlyadapted for use instorm window frames of the self-storing type which receive an upperglazed sash and a sliding lower glazed sash which may be raised or.stored' during the summertime to provide an. opening in the lower halfof the storm window frame; this opening may be screened with a slidingscreened sash. which is adapted to be raised or stored during thewinter-time, whenv the lower glazed sash is in use. This application isa continuation-in-part application with respect: to our co-pendingapplication Serial N 0. 853756 for'Storm Window,. filed April 6, 1949,now U; S. Patent No. 2629.143" issued February 24,. 1953 and withrespect to our pending application Serial No. 144,386 forStorm Window,filed- September 7, 1949, now U. I S. Patent No. 2,595,016 issued April29, .1952.

It is an advantage of storm window frames made'according to ourinvention that theymay be made of extruded metal, preferably aluminum orstainless steel, having channel or box sections, thereby providing thepermanence and strength-of metal while being light-weight for shippingand handling and economical tov produce. Storm windows made according toourinvention are closely fitting, andmay be produced for closertolerances than has been heretofore possible with, wood or metal stormwindows of the self-storing. type.

Because of the close fits necessary to obtain the desirablewind-tightness in storm windows, the so-called' self-storing stormwindows heretofore availablehave not satisfied this-need. Such failurehas been attributable largely to the fact that the prior art stormwindows have. had to be custom built/i. e-., made on special. order andfitted on the job in order to compensate or correct for the inevitable.warped, misaligned and/or out-of-plumb. construction inevitably found inthe casings of primary windows in wood or masonrybuildings- The.carpentryantinsmith work involved in fitting prior art wood or metalstorm windows not only was very expensive butcould not equal theclose-tolerance precision construction of our windows. Our storm windowframes may be either cut and built to stock sizes in the factory or cutin the factory, shipped, knocked-down, and assembled on 'or near thesite of installation. Though our storm window frames are preferablyproduced in stock sizes, such stock-size frames may be easily fitted tothe wood or masonry casing of a primary window, despite the variationsnormal 1y found in such. window casings. This substantial advantage, isobtained by providing an integral waste strip or flange around theoutside of our storm window frames.

Other advantages of this invention will be apparent from examination ofthe following specification and the drawings in which:

Figure 1 is an outside front elevation'of a storm window frame madeaccording to our invention.

Figure 2 isla side elevation of the structure shown in Figure l.

Figure 3 is an, enlarged sectional detail of the sill construction takenon the line 33 of Figure 1.

Figure 4 is an enlarged sectional detail of the frame jamb, taken alongthe line 6-4 of Figure 1.

Figure 5 is an enlarged sectional view of the frame lintel taken alongthe line 55 of Figure 1.

Referring to the drawings, in which like reference characters refer tolike parts, our storm window frame is referred to generally by thereference character Ill. The frame is comprised of a channeled lintelmember I I. channeled jamb members I2 and I3, and a' sill member I4, allbeing preferably formed of channels of stainless steel or likecorrosion-resistant metal to provide the strong and rigid box or channelsections disclosed in the several detailviews and discussed below.vAlthough the, frame members II, I2, I3 and I 4 areof a complexcross-section, they are formed economically and accurately either by theextrusion of molten aluminum or like metal through suitable extrusiondies or by rolling the section from coiled steel strip. Long lengths ofsuch extruded. stockmay be cut to window lengths;

Specifically, the lintel II iscut to the window Width required fromstandard deep channeled stock of the cross-sectionshown, in Figure 5- ofthe. drawings. Such lintel stock comprises, in cross-section, a. bodyportion .I It having sash receivingchannels IIII'I, H2, and H3 and anintegral, outwardly extending flange or wastestrip H4 provided with theparallel break-off grooves H5. In the particular embodiment shown, theends of the window lengths of the lintel stock are suitably mitered toform the mitered joints with the jambs I2 and I3, as shown. The jambs I2and I3 are formed from lengths of standard stock of similarcross-section, the cross-section of the jamb- I2 being illustrated inFigure 4. Each jamb may comprise a box section I20 having sash receivingchannels I2I, I22 and I23 (corresponding to the lintel channels III, H2and H3) and an integral flange of waste strip I 24 provided withparallel breakoff grooves I25.

It should be noted that the waste strip I24 of the jambs I2 and I3occupies the same relative position with respect to its sash receivingchannels as the waste strip II4 of the lintel II occupies with respectto its sash-receiving channels, so that, when the lintel II and jambs I2and I3 are joined with their respective sash-receiving channels inalignment, the waste strips I24 and H4 will form a continuous groovedfin around the top and sides of the frame I0.

As may be seen in Figure 3, the sill 24 may comprise a length ofextruded stock having a substantially box section and comprised of asill portion 24! which may have a bevelled sealing ridge 2M which, withthe ridge 242, defines a screen sash receiving channel 243. The sillportion carries a dependent sealing fin. 244 and a seating fin 245.

. As a final assembly operation, the sill I4 is joined to the jambs I2and I3. The sill 14 comprises a hollow body or box portion I46 having aslot adapted to receive a rubber sealing strip I which engages theseating fin 245. The body portion I40 carries a sealing fin I42 which isengaged by the fin 244 of the sill 24.. The body portion I40 alsocarries the integral waste strip I44 provided with break-off groovesI45. The length of the extruded stock from which the sill I4 is cut ismilled at the ends to permit the body portion I40 to be received betweenthe jambs I2 and I3 and the waste strip I24 is notched, as shown in Fig.1, to receive the ends of the jambs I2 and I3. The notches in the thinwaste strip I44 are easily trimmed, as by filing,

to compensate for any accumulation of manufacturing tolerance and topermit the sill I4 to seat firmly on the seating fin 2 15 of the sill24.

Storm window frames constructed and assembled as above described arepreferably made up in stock sizes to carry sashes of the approximatewidth of the sashes of the primary window on which the frame is to bemounted. The proportions of the several waste strips I24 are then suchthat their total width will exceed the width of the opening between thecasing jambs in any primary window casings. The height of a storm windowis also selected so that the waste strips H4 and H14 will exceed theheight of the opening between the sill and the lintel of the primarywindow casing. To fit the storm window, all that need be done is tobreak off the waste strips along the break-off grooves II5, I25 and I45until the waste strips fit against the blind stops of the casing, theends of the sill waste strip I44 being trimmed as necessary. The wastestrips are then drilled and screwed to the casing.

While we have disclosed a preferred and tested embodiment of our stormwindow frame, it is understood that other specific embodiments may befabricated without departing from the scope of our invention as definedin the followin claims.
